Can we replace computed tomography angiography by contrast-enhanced ultrasound in the surveillance of patients submitted to aortoiliac aneurysm repair?

Objectives: This study was designed for evaluation of CEUS (contrast-enhanced ultrasound) for the detection of endoleaks after EVAR (endovascular aortic aneurysms repair) as an alternative to CTA (computed tomography angiography), the gold standard in post-EVAR surveillance.

Methods: Post-EVAR surveillance of patients who underwent CEUS and CTA was retrospectively analyzed to compare the accuracy of CEUS compared to CTA. For that, the following parameters were analyzed: the largest aneurysm diameter, type of endoleaks, and the time elapsed after EVAR using both surveillance tests.

Trashepatic left gastric vein embolization in the treatment of recurrent hemorrhaging in patients with schistosomiasis previously submitted to non-derivative surgery.

Context: Non-derivative surgical techniques are the treatment of choice for the control of upper digestive tract hemorrhages after schistosomotic portal hypertension. However, recurrent hemorrhaging due to gastroesophagic varices is frequent.

Objective: To evaluate the outcome of treatment based on embolization of the left gastric vein to control the reoccurrence of hemorrhages caused by gastroesophagic varices in patients with schistosomiasis previously submitted to non-derivative surgery.

[Stent thrombosis in aortic aneurysm: evaluation by multidetector CT].

Objective: Evaluate the imaging findings of thrombosis in a series of patients submitted to endovascular repair of aortic abdominal aneurysm.

Methods: MDCT images of 30 patients submitted to endovascular repair of aortic abdominal aneurysm were obtained by a 64 slice scanner, 5 to 29 months after the endovascular treatment.

Results: Thrombosis was diagnosed in 10 patients (33.
